I know there is Bootcamp v3,4, and 5. I know that certain versions of Bootcamp were available depending on which version of MacOSX was purchased. And that certain versions of Bootcamp only support certain versions of Windows. See this link. What I don't know is what version of Bootcamp was released with which versions of MacOS? This was my premise and it may be in error: Different versions of the MacOS only support specific versions of Windows. Be sure to understand what version of Windows your Mac can support. For example Snow Leopard & Lion (10.6, 10.7) only supports Windows 7 and 8. I believe Leopard (10.5) supports Vista. So can any version of MacOSX 5 or newer run any version of Bootcamp? If you have a good link which describes this relationship, I'd appreciate it. Thanks!
